Diethylene glycol dibenzoate

Diethylene glycol dibenzoate (CAS 120-55-8), commercially known as Benzo Flex 2-45 and abbreviated as DEGDB, is a benzoate ester plasticizer used across polymer, coating, and adhesive systems. It functions as a primary or secondary plasticizer, improving flexibility and processability in a range of polymer matrices. In PVC formulations, DEGDB delivers effective plasticization with low volatility.

This makes it suitable for flooring, wall coverings, and flexible film applications where long-term performance is required. Adhesive and sealant manufacturers use it to adjust tack, flow, and open time. It is effective in both water-based and solvent-based systems. In coatings and printing inks, it acts as a coalescing aid and film-forming plasticizer, improving substrate adhesion and surface finish.

Personal care formulators incorporate it as a plasticizer in nail lacquers and film-forming cosmetic products. Diethylene glycol dibenzoate is supplied as a clear, pale liquid in drum and IBC quantities. These formats are suited to industrial procurement volumes. It is available in technical and industrial grades, with purity specifications typically at 99%+ for demanding polymer and coating applications.

Buyers should confirm grade suitability against specific formulation requirements. This is particularly important where low-color or low-acid-value material is specified for the final product.
